[PATCH 1/1] Staging: hv: util: kvp: Cleanup kvp_get_domain_name()
Cleanup kvp_get_domain_name(). If getaddrinfo() fails, deal with it properly (this can happen if no IP address has been assigned). Also, don't specify a specific service in the call to getaddrinfo() to make this code as generic as possible. Lastly, move the call to gethostname() after the local variables. Signed-off-by: K. Y.
